It is recommended to switch to using a compatible desktop environment if your desktop environment is listed below as incompatible.

Always Compatible and no Workarounds Required

LXDE (not LXQt)

XFCE

MATE

MATE (the fork of GNOME2) is not included with certain distros, such as Ubuntu 12.04 and Ubuntu 14.04. You can however install it from http://mate-desktop.org/ on those 2 versions of Ubuntu and on other distros.

Ubuntu 14.04 includes some MATE packages, but not enough of them to provide the MATE desktop environment. See the above note about installing MATE on Ubuntu 14.04.

Always Compatible, but Trivial Workarounds Required

IceWM

In X2Go Client, you must specify the Session Type as: Custom Desktop: icewm-session

OpenBox

In X2Go Client, You must specify the Session Type as: Custom Desktop: openbox-session

Compatibility and Workarounds depend on what version

GNOME

GNOME 2: Compatible and no workaround required

GNOME 3.0 through 3.6: “GNOME Fallback Mode” must be installed. This is included with most, if not all distros.

GNOME 3.8: “GNOME Flasback Mode” 3.8.x must be installed. It is seldom included with distros. There are bugs with it. Using GNOME 3.8 with X2Go is not recommended.

GNOME 3.10: “GNOME Flasback Mode” 3.8.x may be compatible, but there are even more bugs with it. It is seldom included with distros. Using GNOME 3.10 with X2Go is not recommended.

GNOME 3.12 and later: TBD, but probably not compatible. Using GNOME 3.12 and later with X2Go is not recommended.

GNOME Classic Mode is not the same as GNOME fallback mode or GNOME Flashback mode. GNOME Classic Mode is not compatible with X2Go.

We might be able to support Gnome 3.14, especially for RHEL7/EPEL7, given enough $$$ and round tuits (https://en.wiktionary.org/wiki/round_tuit), but support for newer versions seems doubtful, due to certain design decisions made by the Gnome developers.

KDE

KDE 3: Compatible and no workaround required

KDE 4: Compatible and no workaround required

KDE 5: Incompatible due to plasmashell requiring GLX 1.3 We have received several reports that KDE 5 now works with X2Go, even though it takes a long time to initialize the session. If you're interested in running KDE 5 via X2Go and run into issues, please join the X2Go-User Mailing List or, if you are certain you've found a bug, subscribe to X2Go-Dev and file a bug report.

UNITY

Ubuntu 12.04: Compatible, as long as package “unity-2d” is installed. By default with “Ubuntu Desktop”, it is.

Ubuntu 12.10 and later (including 14.04): Not compatible

Cinnamon

Cinnamon 2.2 (Linux Mint 17 “Qiana”): Not compatible. Cinnamon reverts to “fallback mode”, which is not as good as regular “cinnamon” nor “cinnamon2d”. If you wish try try it in anyway, specify the Session Type as: Custom Desktop: cinnamon-session-cinnamon2d
